DELlNTlNG-'NIACHINE SPECIFICATION forming part of Letters Patent No. 791,318, dated May 30, 1905.

Application filed May 5, 1904. Serial No. 206,552.

- To all whom, it may concern:

Be itknown that LWINEIELD S. CANNADAY,

-Washington Court-House, in the county of Fayette and State of Ohio, have invented a new and useful Delinting-Machine, of which the following is a specification.

- This invention relates to improvements in machines for removing the lint from cottonseed; and the Objectis to provide a novel structure of a simple nature wherein the seeds are subjected to a thorough scouring to completely remove the lint therefrom without cracking or injuring said seed. v

Another object is to provide a machine of this character that will occupy comparatively little floor-space and is so constructed and arranged that the parts are readily accessible for the purpose of repair and renewal.

Another and very important object is to construct the machine so that the different grades of lint will be automatically sorted and separatelydelivered, thereby securing a more Valuable product.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the machine. Fig. 2 is a vertical sectional view therethrough. Fig. 3 is an end elevation .of said machine. Fig. 4 is a detail sectional view through a portion of one of the retarding devices. Fig. 5 is a detail perspective view of one of said retardingdevices, showing the arrangement of the retaining rods or wires.

Similar reference-numerals indicate corresponding parts in all the ligures of the drawings. v

In the embodiment illustrated an upright casing 6 is employed, comprising side walls, a top, and a bottom mounted upon a suitable base-frame 7. On the central portion of the top is mounted a hopper 8, the lower end of which is-alined with an opening 9, formed in the top of the casing. 4The bottom of said casing directlybeneath this hopper is provided with a suitable delivering device (shown in the form of a screw conveyer 10) that distending from the lower portion of the casing.

'are ground or sharpened.

is journaled in suitable adjustably-supported boxes 15 and projects at one end through the casing. Upon the projecting end is mounted a suitable driver, shown in the present instance as a sprocket-wheel 16. The shaft carries within the casing a plurality of very thin lsteel-plate disks 17, spaced apart by suitable washers 18. These disks are providedvwith peripheral tangentially-disposed hook4 portions 19, the outer edges 2O of which As a result of this arrangement open-sided laterally or tangentially disposed pockets 21 are provided, that extend the length of the retarder and have open slots therethrough formed by the spaces between the disks. As shown in Fig. 2, the retarders are of suiiicient diameter to project beneath the hopper and are mounted so that the open mouths of the pockets when disposed beneath said hopper are uppermost. They are revolved to carry the portions beneath the hopper downwardly, this revolution being accomplished by a suitable sprocket-chain 22 kor other element engaging the wheels 16 and also a sprocket 23, mounted upon the projecting end of the shaft of the screw conveyer 10. Idlers 25 maintain operative engagements between the wheels and the chain. An agitator or feeding device 26 is located in the lower end of the hopper 8 and is also preferably driven from the uppermost shaft'li by suitableysprockets'26 and a connecting-chain 27.

Ooacting with each of the retarding devices above described is a rotary delinting-brush 28, journaled in boxes 29, secured to the standards 13. The shafts 30 of these brushes also project beyond the casing and carry on theirprojecting ends sprockets 31, engaged by an endless chain 82. The mechanism is so arranged that the brushes will be operated at a very high rate of speed as compared with IOC the retarders. As shown in Fig. 2, the inner portions of the brushes overlap the retarde rs, and thus operate successively in the pockets thereof during the revolution of the same. rlhese overlapping portions are located in a seed passage-way, one wall of which is defined by the brushes and triangular bars 33, disposed between the inner portions thereof. The other wall is formed ofretaining rods or wires 34, extending from the top to the bottom of the casing and passing between the spaced disks, the space between the wires being, preferably, just sufficient to permit the passage of said disks.

The side of the casing in rear of the delinting-brushes is formed into lower and upper air-conduits 35 and 36, which are alined, the former terminating substantially midway between the top and bottom of the vcasing and having an outstanding delivery spout 37. This conduit has communication by means of inlet-openings 38 with the lower portion of the interior of the casing directly adjacent to the lower portions of the three lowermost brushes. The upper conduit 36 terminates at the top of the casing in an outstanding delivery-spout 39 and is provided in its inner wall with inlet-openings 40, communicating with the interior of the upper portion of the casing contiguous to the three upper brushes. Directly below the inlet-openings 38 and 40 are triangular deflector-blocks 41, constituting, in effect, partitions between the rear or outer portions of the brushes and directing the lint therefrom to the openings 40.

A single fan 42 is preferably employed for delivering blasts or drafts of air through both the conduits 35 and 36, said fan being mounted in a casing 43, arranged at the lower end of the machine and having a divided deliveryspout 44, one portion of which communicates directly with the conduit 35, the other being extended, as shown at 45, to the upper conduit 36. The fan is driven in any suitable manner, shown in the present instance from a sprocket-wheel 46, which meshes with the chain 32, and having a sprocket connection 47 with the fan-shaft 48. In connection with the separate conduits lint-collecting means are employed in the form of rollers or drums 49, journaled on the exterior of the casing and extending across, but in spaced relation to, the delivery-spouts 37 and 39. These rollers are connected by a sprocket-chain 50 and are driven in any suitable manner.

The operation of the machine may be briefiy described, as follows: Assuming the various parts in operation, it will be apparent that the brushes rotating very much faster than the retarders will operate through the same, and because of the sharpened edges no resistance will be aiforded bythe fingers or hooks thereof. If now cotton-seed is passed into the hopper 8, it will be fed upon the uppermost retarder, or, more accurately, upon the portions thereof projecting into the passageway. As already explained, the hooks thereof are moving downwardly with their open sides uppermost, so that the seeds will drop into the pockets, and the brush will thoroughly clean and scour the same, detaching the longer lint and carrying it rearwardly. Said seeds are securely held by the pockets, and, moreover, the brush while passing between the disks is stiened thereby` so that the action upon the seeds is at all times assured and peculiarly etlicient. Said seeds will be retained in the passage-way and expelled from the pockets of the uppermost retarder by the wires or rods 34, and consequently they will drop into the succeeding retarder, where they will be acted upon by the next brush, and thus the seeds will pass successively through the retarders until they reach the conveyer at the bottom. It will be apparent that during such passage said seeds will be continuously turned over and thoroughly acted upon by the brushes, so that when they reach the bottom they will be thoroughly delinted. The lint is carried rearwardly by the various brushes and is drawn by the suction action of the fanblasts through openings 38 and 40 into the conduits, thence delivered from the spouts against the rollers, where it is collected. As the uppermost sets of delinting devices secure the better grade of lint, it will be seen that this better grade will consequently be delivered to the upper roller, while the shorter and less valuable grade removed by the lower set will in like manner be delivered to the lower roller. Consequently the lint obtained is automatically graded. When in the course of time the disks become worn, they can he properly dressed and when replaced can be adjusted to the brushes by moving the bearings 15 toward the said brushes.

It will be obvious that any number of the coacting sets of retarders and delint'ers can be employed as desired and, furthermore, that the same can be driven in any suitable manner. Other changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacriiicing any of the advantages of the invention.
